FIELD OF THE INVENTION

This invention is in the field of anticoagulant therapy, andspecifically relates to compounds, compositions and methods forpreventing and treating thrombotic conditions such as coronary arteryand cerebrovascular disease. More particularly, the invention relates topolycyclic aryl and heteroaryl substituted 1,4-quinone compounds thatinhibit serine proteases of the coagulation cascade.

BACKGROUND OF THE INVENTION

Physiological systems control the fluidity of blood in mammals [Majerus,P. W. et al: Anticoagulant, Thrombolytic, and Antiplatelet Drugs. InHardman, J. G. and Limbird, L. E., editors: Goodman & Gilman's ThePharmacological Basis of Therapeutics. 9th edition. New York,McGraw-Hill Book Co., 1996, pp. 1341-1343]. Blood must remain fluidwithin the vascular systems and yet be able to undergo hemostasis,cessation of blood loss from a damaged vessel, quickly. Hemostasis orclotting begins when platelets first adhere to macromolecules insubendothelian regions of an injured and/or damaged vessels. Theseplatelets aggregate to form the primary hemostatic plug and stimulatelocal activation of plasma coagulation factors leading to generation ofa fibrin clot that reinforces the aggregated platelets.

Plasma coagulation factors include factors II, V, VII, VIII, IX, X, XI,and XII; these are also called protease zymogens. These coagulationfactors or protease zymogens are activated by serine proteases leadingto coagulation in a so called “coagulation cascade” or chain reaction[Handin, R. I.: Bleeding and Thrombosis. In Wilson, J., et al. editors:Harrison's Principles of Internal Medicine. 12th Edition, New York,McGraw-Hill Book Co., 1991, p.350]. Coagulation or clotting occurs intwo ways through different pathways. An intrinsic or contact pathwayleads from XII to XIIa to XIa to IXa and to the conversion of X to Xa.Xa with factor Va converts prothrombin (II) to thrombin (IIa) leading toconversion of fibrinogen to fibrin. Polymerization of fibrin leads to afibrin clot. An extrinsic pathway is initiated by the conversion ofcoagulation factor VII to VIIa by Xa. The presence of Tissue Factor andVIIa accelerates formation of Xa in the presence of calcium ion andphospholipids. Formation of Xa leads to thrombin, fibrin, and a fibrinclot as described above. The presence of one or more of these manydifferent coagulation factors and two distinct pathways of clottingcould enable the efficacious, selective control and better understandingof parts of the coagulation or clotting process.

While clotting as a result of an injury to a blood vessel is a criticalphysiological process for mammals such as man, clotting can also lead todisease states. A pathological process called thrombosis results whenplatelet aggregation and/or a fibrin clot blocks (i.e., occludes) ablood vessel. Arterial thrombosis may result in ischemic necrosis of thetissue supplied by the artery. When the thrombosis occurs in a coronaryartery, a myocardial infarction or heart attack can result. A thrombosisoccurring in a vein may cause tissues drained by the vein to becomeedematous and inflamed. Thrombosis of a deep vein may be complicated bya pulmonary embolism. Preventing or treating clots in a blood vessel maybe therapeutically useful by inhibiting formation of blood plateletaggregates, inhibiting formation of fibrin, inhibiting thrombusformation, inhibiting embolus formation, and for treating or preventingunstable angina, refractory angina, myocardial infarction, transientischemic attacks, atrial fibrillation, thrombotic stroke, embolicstroke, deep vein thrombosis, disseminated intravascular coagulation,ocular build up of fibrin, and reocclusion or restenosis of recanalizedvessels.

There have been several reports of non-peptidic and peptidic 2-pyridonecompounds that act as an inhibitor of a coagulation factor present inthe coagulation cascade or clotting process. In U.S. Pat.

Formula (I) compounds of this invention possessing hydroxyl, thiol, andamine functional groups can be converted to a wide variety derivatives.A hydroxyl group in the form of an alcohol or phenol can be readilyconverted to esters of carboxylic, sulfonic, carbamic, phosphonic, andphosphoric acids. Acylation to form a carboxylic acid ester is readilyeffected using a suitable acylating reagent such as an aliphatic acidanhydride or acid chloride. The corresponding aryl and heteroaryl acidanhydrides and acid chlorides can also be used. Such reactions aregenerally carried out using an amine catalyst such as pyridine in aninert solvent. Similarly, carbamic acid esters (urethanes) can beobtained by reacting a hydroxyl group with isocyanates and carbamoylchlorides. Sulfonate, phosphonate, and phosphate esters can be preparedusing the corresponding acid chloride and similar reagents. Compounds ofFormula (I) that have at least one thiol group present can be convertedto the corresponding thioesters derivatives analogous to those ofalcohols and phenols using the same reagents and comparable reactionconditions. Compounds of Formula (I) that have at least one primary orsecondary amine group present can be converted to the correspondingamide derivatives. Amides of carboxylic acids can be prepared using theappropriate acid chloride or anhydrides with reaction conditionsanalogous to those used with alcohols and phenols. Ureas of thecorresponding primary or secondary amine can be prepared usingisocyanates directly and carbamoyl chlorides in the presence of an acidscavenger such as triethylamine or pyridine. Sulfonamides can beprepared from the corresponding sulfonyl chloride in the presence ofaqueous sodium hydroxide. Suitable procedures and methods for preparingthese derivatives can be found in House's Modern Synthetic Reactions, W.A. Benjamin, Inc., Shriner, Fuson, and Curtin in The SystematicIdentification of Organic Compounds, 5th Edition, John Wiley & Sons, andFieser and Fieser in Reagents for Organic Synthesis, Volume 1, JohnWiley & Sons.
